Don't compare Blockchain and cryptocurrencies, these are absolutely different areas! While blockchain is a technology, bitcoin is just one of its use cases.
Where most of these 'blockchain' companies are going to screw up is by believing they, or mysteriously altruistic strangers, can run a properly useful and secure chain without a financial incentive. Why would you bother unless there's something in it for the person providing the actual platform you're hammering?
If it's between interlinked and likeminded entities then there are and always have been shared databases for that.
It's exactly the same as intranet vs internet. Masses of companies reckoned they could create their own internet that was 'better' then reality dawned on them as they were roundly ignored by people running towards the real deal.
